Anaconda supports python 3.3, it just defaults to 2.7 To make a 3.3
environment you have to use their package management tool, conda. (you can
skip having to download the monster sized installer of 2.7 by using
miniconda which is just a script that installs a minimal conda system and
lets you decide which pieces you want, including setting up a 3.3 only
environment) here is a list of all the packages it supports for each
version of python http://docs.continuum.io/anaconda/pkgs.html numpy 1.8.0
is in there.
